THOMAS CARROLL, OF DAYTON, O HIO, ASSIGNOR, BY MESNE ASSFGNME NTS, TO THE NATIONAL CASH REGISTER- COMPANY, OF DAYTON, OHIO, A CORPORATION OF OHIO,

(INCORPORATED IN 1906.)

CASH-REGISTER,

s ecification of Letters Patent. t t Aum 10, 1 15,

Application filed July 22, 1905. Serial No. 270,786.

To all whom. it may concern 7 Be it known that I, THOMAS CARROLL, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which I declare the following to be a full, clear, and exact description.

This invention relates to improvements in cash registers and has among its objects and purposes to provide improved devices whereby the operator may at any desired time secure a printed record of the so-called summary totals or the grand total, the summary total being the total of the amounts registered between any two periods, and the grand total being the total of all the amounts registered from the time of the first transaction up to the time of the lastone; and another object is to provide means for printing in'separate columns the various items for the difierent sets of transactions; and accompanying these devicesare certain locking features which form an ad vantageous accompaniment to the fulfilment of the above-mentioned objects.

With these and inci lental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter specifically described with reference to the drawings which accompany and form part of this specification.

Fig. 19' represents a-rear elevation of the "flash operating mechanism cooperating with the shaft which operates the laterally shifting printing c'z'trriage. Fig. represents a ,detail view of the flash operating mechakeys, a series of clerks numerals keys'and' a series of special transaction keys which when depressed set certain parts for the net-- essary operations of registering, recording" and indicating, the completion of the oper ation of the machine being effected by the revolution of a crank handle or other suitable driving means The operation of the amount'lieys results in the setting of certainregistering bars or segments to differential positions and upon the subsequent operation of the crank handle these registering segments are restored to normal position, and upon such restoration to normal position the counter is actuated and the printingwheelsare set by means of certain idle pinions which fornr an intervening connection to transmit the diiferential movements of the registering segments to the counter and to the printing wheels. At the same time the indicators are set to positions corresponding to the: values ofthe amount keys depressed; this setting of the indicators in each case'being' effected without the necessity of returning the indicators to normal zero= position at thebeginning of the operation of the machine prior totheir renewed setting: movement; Means are also provided by which when any one of the special transaction keys is depressed the counter is thrown out of operation.

The amount keys, the clerks numerals keys and the special transaction keys are appropriately connected withtype wheels and a printing: mechanism isprovided" which prints both upon a detail strip and a check, these printing wheels being all returned to normal position at thee'nd of each operation of the machine.

In order to secure the printing of the socalled summary total a specialsummary total key is provided; the machine isprovided with both a summary total counter and also with a grand total counter, which latter is thrown into mesh with thesummary total counter at each operation of the machine. Upon the pressing of aspeci'al summary total key thesuniinary total counter is connected up to the amount printing wheels so that when the summary total counter is reset to zero, the printing wheels will be set to positions corresponding to the amounts shown by the summary total counter, and thereupon with: the subsequent actuation of the operating handle the impression is taken of this amount thus set up upon the printing wheels. The summary total is thus therefore left in cleared condition, having been completely reset to zero and upon the registration of subsequent transactions the summary total counter will now give the total of the amounts registotal counter is coupled to the printing wheels so that upon the turning to zero of the grand total counter the printing wheels areset to show the amount corresponding to that'which' was registered upon the grand total counter'and uponthe operation of the machinethis grand total amount is printed. The summary total is in-each case struck before the grand total i-s-struck, and after the grand total is struckthe summary total counter is reset to zero,v since the resetting of the grand total counter to zero serves to register itsamount upon the summary total counter.

In or'derto print the various items of the special transactions in a column separate from that of the cash transactions the detail stirip is'mounted upon a shifting printing carriage and the operation of any one of the special: keys serves to set parts such that upon" thesu'bsequent operation-'- of the handle the detail strip carriagewill be shifted laterally so as to effectthe printing. of these itemsin' a difi'erent column; and also upon the registering. of such special transactions the flash which conceals the indicators is retained in concealing position and remains so until thenext cash transaction.

lVith: this-general description of the operation of the machine, the specific parts thereofi will now be described more in detail.

Referring to Fig. 1, it will be seen that there are five'banks of amount keys 30, two banks of clerks numerals keys 31 permitting the recording of clerks numerals from 199, and a series of special transaction keys 32, a summarytotal printer setting key 33 and a grand total printer setting key 84:, these latter two keys being merely for the purpose" of setting the printing segments to indicatethe printing of a summary total or a grand total, and: being. distinct from the summary total and grand total operating keys to be later described.

A crank handle3 5 supplies the main actuating power of the machine and effects the rotation of the two main operating. shafts by means of gearing best shown in Fig. 21. The" handle itself is fast to a small gear wheel 36 which meshes with a larger gear wheel 37 mounted upon the outer end of the upper" operating shaft 38, and the gear 37 in t'urn mesh-es with acompanion gear wheel 39 fast upon the outer end of the lower opera-ting shaft 40. These two shafts 38 and 0 are" provided with the various: operating cams for actuating the different parts of the machine as shown in Fig. 16.

Fast upon the shaft 38 and just inside the right hand frame of the machine is another gear wheel 41 (see Fig. 16) which meshes with a smaller gear wheel 4.2 (see Fig. 21) which is fast upon the right-hand end of an auxiliary operating shaft 43 which effects the shifting of the/printing carriage in the manner to be described.

Register m9 segments-The operation of the registering segment by the keys will now be described. The key shanks 45 (see Fig. 2) extend through suit-able apertures in a plate 46 attached to the front of the machine and are normally spring-messed outward by means of springs 47 and are limited in their out-ward movement by stop pins 48. *Ixtending across the lower portion of the machine is a transverse shaft &9 upon which are pivoted the registering segments 50 which at their upper ends are formedwvith rack teeth 51 which mesh with pinions mounted'loosely upon a transverse shaft these pinions serving to transmit the differential movements of the registering segments to the counter and printing wheels as later described. There is one of these registering segments for each bank of amount keys but there are none for the two banks of clerks numerals keys or for the special transaction wheels, the printing wheels for these sets of keys being set in a manner different from the setting of the amount printing wheels. Cooperating with each of said registering segments 50 is an indicator setting segment which is pivoted upon the transverse shaft a9 but at its pivotal point is formed with a slot 55 to permit the raising of these segments for the purpose to be presently described. The forward sides of the registering segments 50 are formed with steps 56 which are engaged by the pins l8 of the .various keys so that upon the pressing inward of any key the segments 50 are rocked to a greater or less extent according to the key depressed, these differential movements being such as toeffect the necessary gradua tions of registering movements from 19 corresponding with the values of the keys. The segments 50 are normally locked in forward position and are released by means of key detents and are also prevented from overthrow movement by key detents as will later be described. On the upper end of the indicator segments 5% are formed teeth 57 which are arranged to engage teeth 58 formed in a block 59 fast on the side of the registering segment In order to raise the indicator segments 5% into engagement with these teeth 58 the following device is provided, as best shown in detail in Fig. 3. The transverse shaft 49 is a rock shaft, and it has fast upon it two upwardly extending arms 60 which are formed with cam grooves 61 into which projects an ant1-fr1ct10n roller '62 which projects from the side arm of a restoring frame 63, there being two of these side arms. connected by a transverse restoring bar 64;, which bar extends through slots 65 formed in the indicator segments 54. so that when the restoring frame is lifted vertically the restoring bar 64 will also lift the indicator segments 54: into engagement with the teeth 58 of the block 59 formed on the side of the registering segments 50. A rocking of the shaft 49 to effect this raising of the restoring frame 63 is effected by means of a link (56' (see Fig. 6) attached at the forward end to an arm 67 (see also Fig. 1) which is fast upon the rock shaft -19; the rearward end of the link 66 is bifurcated to st addle the lower operating shaft 40 and is formed with a pin 68 (see 69 formed in a disk 70 fast upon the operating shaft 40 so that when said shaft is :rotated in the direction shown by the arrow iniFig. 6 the link 66 will be drawn slightly rearward and therebywill rock the shaft 49 and hence rock the arms 60 in such manner as to cause the walls of the cam grooves (31 to lift the rollers 62 and thereby raise the restoring frame 63 vertically the pivotal lower end of the restorim frame also bein D b slotted on the shaft 49 to permit this vertical movement. As soon as the restoring bar has thus been raised vertically it is rocked forward by the following means: Pivoted to the forward upper portion of each side arm of the restoring frame is a link. 71 (see Figs. 2, 2 and 3) which link that the link is forced forward thereby i carrying the restoring'frame G3 and the re storing bar 6% forward holding them in this position until almost the end of the operation of the machine, at which time the restoring frame is again dropped to lower position and the link 71 is retracted to normal position carrying the restoring bar 6-]: back to normal rearward position. This forward movement of the restoring bar 6% acts to restore the registering segments 50 to normal composition by reason of the bar 6 f striking the projections 75formed onthe lower rearward sides of the registering segments 50, and since the indicator segments have during this time been elevated into engagement with the blocks 59 formed 011 the sides of the registering segments 50, these segments 54- will thus be moved forward to an extent corresponding to the previous displacement of the registering segment 50 by the amount keys, and these indicator segments 54. will remain in this position'until the restoring bar 64 returns to normal rearward position and thereby carries the indicator segments back with it to normal rearward position. The indicator segments 54: are arrested in their normal rearward position by means of a transverse shaft 114.

Indicator setting mechcmz'sm.-This forward setting movement of the indicator setting segments 54 is utilized to set the indicators in the following manner. The segments 54 are formed with rearwardly extending arms 79 (see Fig. 2) to which are pivoted links 80, to each of which links 80 is pivoted at 81 a power application bar 82, which at its rearward end is pivoted to another vertically extending link 83 attached to the rearward end of a bell crank formed indicator setting segment 84, which segment meshes with a pinion 85 fast on the side of the indicator 86. A second set of segments 87 serve to connect the duplicate indicators for indicating at the back of the machine as well as at the front of themachine in a well known manner. To each indicator is made fast an alining wheel 88 which is engaged by an alining pawl 89 which is suitably operated from one of the main operating shafts of the machine to release the indicators while they are being set and to lock the same after they have been moved to proper position and retain them in such po sition until the next operation of the ma chine. The vertical links 83 extend through slots formed in transverse bars 90 of the mam frame of the machine which slots serve to guide the links in their vertical movements and the links are provided with noses 91 engaging said bars, these noses serving to limit the vertical extent of movement of the links 88 between the zero and the 9 positions of the indicators. To the middle portion of each power application bar 82 is pivoted a downwardly extending bar 93 which extends into slots formed in the transverse guide bar 94: of the machine. These bars 93 are also formed with slots 95 at their middle portions to surround the lower main operating shaft 40. On one side of each bar 93 and above the slot 95 is an antifriction roller 96 which is arranged to be engaged by a cam 97 fast upon the main operating shaft and adjacent to the bar 93; and upon the other side of each bar 93 is another anti-friction roller 98 situated below the slot 95 and arranged to be engaged by a cam 99 also fast to the shaft L0 and on the other side of the bar 93, the anti-friction roller 98 and cam 99 being shown in dotted lines in Fig. 2 and the roller 96 and cam 9-7 being shown in full lines in said figure. In the normal condition of the machine when the indicator stands at zero, the parts are in the position shown in Fig. 2; but when any indicator segment 54: is swung forward by the operation of the restoring bar 64 in the manner previously described, the link 80 is raised and'since the indicator segment 54; is locked. to the registering segment 50, and the latter has been returned to normal position, the pivotal pin 81 will. therefore be held in a fixed position and becomes a fixed fulcrum point; but the raising of the pivotal point 81 has also raised the bar 82 and thereby raised the bar 93 and consequently also raising the roller 98, and thus upon the operation of the shaft 40 in the direction shown by the arrow, the cam 99 will act upon the roller 98 and draw the bar 93 downward thereby applying power to the bar 82 to rock the same about the fixed pivot 81 as a fulcrum and thus drawing downward the link 83 to set the indicator to an amount corresponding to the amount of movement of the indicator setting segment 54-. As soon as the indicators have thus been set the alining pawls 89 are rocked inward to lock the same in set position, and at the final part of the operation of the machine the restoring bar 64 is returned to normal rearward position thereby carrying the indicator segments 54 back to normal rearward position and returning the pivotal point 81 to normal lower position; and if upon the next operation of the machine no key in this previously operated bank is now operated, the indicator segment 54 will not be moved forward at all but nevertheless will be moved slightly upward vertically to become locked to the block 59 and thus to the stationary registering segment 50 where by the pivotal point 81 is now held positively in its lowermost position and becomes a new fulcrum point for the movement of the bar 82 so that the cam 97 now acts upon the anti-friction roller 96 to rock: the bar 82 about this new fulcrum point and thereby restore the indicator to normal zero position. If however the indicator segment 54k is set twice in succession to the same point by'means of the depression of the same key in any bank upon two successive operations of the machine, it will be apparent that the pivotal point 81 remains the same in each case and that the cams 97 and 99 will have no elevating or depressing effects upon their respective rollers and thus there will be no movement of the indicator but the same will remain in the position to which it was previously set upon the previous transaction; and similarly the extent of movement of the indicator from one amount to another is only enough to .carry it from, one such bank of amount keys, one of these plates b- 7 ing the unlatching plate 100, shown in full lines in Fig. 1 and also shown detached n Fig; 22, and a stop plate 101 shown in dbtted lines in said Fig. 4t. Theseplates' are suitably mounted in guide pieces supported by the main frame of the machine. The

stop plate 101 is formed with V-shaped slots 102 of gradually increasing divergence from the 1 key to the 9 key, the upper wall of each slot however being straight with reference to the direction of the depression of the key, but the distance between the'key pin as and this upper wall of each slot'in creases from the 1 key to the 9? key. Ihis stop plate has a downwardly and rearwardly extending arm 103on the end of which is a pin 101 projecting into a slot'105 formed in the rearward end o'fan' arm 106 extending from the lower pivota l end of the registering segment 50. It w1ll thus be seen that when'the pin as of any key strikes its corresponding stepped portion 56 of the registering segment 50 and rocks the segment about its pivotal shaft49, the rocking downward of the arm 106 will also pull downward upon the arm 103 and will there-y if'ore draw the stop plate" 101 downward and will cause the'upper wall ofits'corresponding V-shaped slot 102 to strike upon thede} pressed pin 48, and thereby the continued iearward movement ofthe segment 50 will; thus be prevented because'of the binding of p the upper wall of theslot against the pin in this manner, and the coiistructionis such that this contact of the wall against the pin takes place at the moment when the pin has just reached the extremity of the V-shaped slot, and thus, any overthrow movement of the segment 50 is absolutely prevented. It will also be seen that it while any key is depressed it'is attempted to depress any key of higher value, this wouldtend to pull the stop plate 101 still farther downward but the plate would be held eiiectually locked against movement by the factthat the pin or the key first depressed is held at the eX- tremity of its slot 102, so that further eX- tended movement of the plate 101 isefi'Lec-J tually prevented; nor could a key of lower valuebe depressed simultaneously to its fullest extent because of the obvious fact that noftwo keys could simultaneouslybeso far depressed that their respective pins could at the same time occupy the extreme end of the -shaped slot, since the stop plate 101 is moved to the dilierent extents for each key depressed.

The latching pl'ate100servesboth to lock the'keys in depre s sedflpositioii and also to unlock the registering segments 50 in the following mannei: T he plateis formed with these sl'otsbeing diiierent fol? each key and being most clea i ly shown in F ig; 22. The

lower endjo f't he sl'ot formedfwith a rightangled portion for thepurpose' of permit ting "the nose formed thereby to latch over i the key pin {18 and hold the key in-depressed positioni' The plates are normally retained in downward position by means of springs 108,; The upper end of the plate 100 has fast upon itsside a single tooth 109 adapted toen'gagetlieiteetli 5115f the registering segment; 50 when the segment is" in normal forward pantie; wherebyto hold the segment latched sue1rp0sition." WVhen' any key is depressed its pin 418 strikes the beveled portion110' of the upper wall-0f the slot 107 and forces the plate l'00 upward and withdraws the tooth 109 from engagement with i the teeth 51 thereby unlocking the register ing segment: to permit'the same to move undei" thecontr'ol ofithekey asheretofore eX- plaiiied,and it'will be observed that thebev eled portioiis 110 are differently situated with res ect to the' different key pinsA S so as to effect the unlocking of the segment 5O slots 107 for each key pin 48, the shape of at differenttimes according to the value of a the key depressed. That is," the pin or the l y or" uppermost key givesfthe least ex te'nt oiiiriovementto tli'e registering segment 50 and" therefore strikes the same at almost the extremity. of the downward movement of the key so'that the'beveled'iedge of theslotoppos'ite this key is at such distance from thatthe pin {18 will contact with'it" just before thepin enemas with the 1 segmenttdand thus the segment will be unloelredijusjt prior toiitsmovement by the, key ;';and the same holds true with reference to the" other'keys, z". e. the a situation of "the by key'pinfjust'pribrlto tlie'timewhen I the pinstrik'es the registering segment 50 sotliat-tlie 'pinfirst'unlecks the segment and their moves the same tothe proper distance The keyboard isfm'ade of the so-called fleXfible type z' fef when one key has'been depressed and is latched in depressed position it'm'ay' bereleased by the depression of anotherke'y without tlie'necessity of a sepa ratereleasekey, but in this particular construction nokey can be releasable except by a key of'higli'er value with the sole exception of the 9* key which is released by the denomination the stop plate 101 has not been moved far enough to block the key pins in this manner and therefore any, key of higher denomination may be depressed, whereupon this pin strikes the beveled .portion 110 of the latching plate and of course releases the previously depressed key by the upward movement of the latching plate in a well known manner. In order to provide for the unlatching of the 9 key it will be observed in Fig. 4 that the upper wall of the V-SllilPGCl slot opposite the 8 key (2'. e.

the next to the lowest) is not exactly straight but is cut away slightly at its forward end, so that when the 9 key is depressed and the stop plate 101 is moved to the extremity of its downward position, the upper wall of the V-shaped slot 102 opposite the pin 48 of the 8 key is not brought low enough to block the pin of this 8 key, but the cutaway portion permits the 8 key to be depressed, whereuponthe pin strikes the correspondingbeveled'portion of the latch plate 100 and hence releases the 9 key.

In order to provide for the unlatching of the keys by the operation of the machine, each latching plate 100 is provided with a rearwardlyextending arm 1.11 formed with a pin 112 projecting into a slot formed in the forward side of .an arm 113 fast to a rock shaft 114. Referring now-to Fig. 6

has formed upon it an anti-friction roller 117 arranged to be struck by a cam 118 fast to the operating shaft 38. The link 116 also has formed upon it a lug 119 arranged to cooperate with a locking shoulder 120 of a disk 121 fast to the operating shaft 38. A spring 122 surrounds the shaft 114 and acts upon the arm to normally draw the link 1 16 forward and consequently throughthe arms 113 to assist in drawing the separate latching plate 100 downward. Upon the operation of any key the movement of the latching plate 100 in the manner just described rocks its arm 113 upwardly and thereby rocks the shaft 114 against its spring tension to carry the lug 119 into the path of the shoulder and thus lock the operating shaft 38 from operation until the key is completely depressed at which time the locking plate 100 spring'sba'ck to normal position and the lug 119 is withdrawn from looking position and the machine is free to be oper ated. Upon such operation of the machine and the consequent rotation of the shaft 38 in the direction shown by-tl e arrow in Fig. 7

segments 50 are being restored to normal position and the keys must be released prior to such restoration. 1

The .two banks of clerks numerals keys and the bank of special transaction keys are providedv each with a latching detent plate 122 as shown in Fig. 7, each of these plates being formed with slots 123 having the usual right-angle portions for retaining the keys in depressed position by engagement with the operating pins 48, but in this case the beveled portions of the upper walls of the slots are uniformly constructed since there are no registering segments connected with these banks of keys and the plates 122 simply serve to latch the keys in depressed position and topermit the flexible release of the same. -Each of the plates 122 has a downwardly extending arm 124 formed with a pin 125 projecting into a slot formed in an arm 126, and these arms 126 are fast to'a collar 127 loosely mounted on the shaft 114, and to this collar is made fast an arm 128 to which is pivoted a link 129 which at its lower end straddles the lower operating shaft 40 (see Fig. 6) and is formed with an anti-friction roller 130 arranged to be engagedfby a single tooth 131 formed upon a disk fast to the shaft 40; and the link 129 also has formed upon it a lug 132 arranged to engage a locking shoulder 133 formed upon a disk 134 fast to the operating shaft. Thus upon the operation of any clerks numerals key or any specialtransaction key, the corresponding movement of the detent plate 122 serves to move the link 129 rearward by means of the afore described intervening connections, and thus carry the lug 132 into the path of the shoulder 133 to lock the machine from operation until a key has been completely depressed in which case the link 129 returns to normal forward position; and upon the subsequent operation of the machine the rotation of the shaft 40 causes the tooth 131 to strike the roller 130 near the end of the operation of the machine and retract the link 129 to release the previously operated clerks numerals or special transaction keys. This release may take place at the end of the operation of the machine since there are no registering segments to be restored in the case of these particular keys as thereis in the case of the amount keys.

Also cooperating with the two banks of clerks numerals keys and the special transaction keys are other detent plates 135 shown in dotted lines in Fig. 6 and in detail in Fig. 23. It is the purpose of these plates to be given a differential movement by the keys and thereby set the printing wheels. Each plate 135 is formed with slots 136 arranged to be engaged by the pins 48 of the keys of these three banks referred to, and these slots 136 are differentially inclined as shown best in Fig. 23 so that the detent plate 135 will be given differential vertical movements corresponding to the key depressed; and each plate is formed at its upper and rearward extremity with rack teeth 137 which are arranged to engage with a pinion 138 (see Fig. 6). There is of course one of these pinions for each of the clerks bank of numeral keys and the bank of special transaction keys and their differential movements are utilized to set the printing wheels for these banks in a manner to be later described. Of course the differential inclination of the slots 136 prevents the simultaneous depression of two keys in the same bank. The plates 135 are returned to normal position by the pressure of the key pins against the same when the keys are returning to normal outward position under their own spring tensions, and are assisted in this return to normal position by means of springs attached to the printing wheels for these banks as will be later described.

fer inter operating mecham'sm.'lhere are two separate counters or registering mechanisms in this machine, one of which will be designated the summary total counter and the other the grandtotal counter, the summary total counter giving the total of certain groups of transactions between certain periods as already explained and the grand total giving the total of all the transactions represented by the sum total of all the various summaries. As has already been stated the registering segments 50 mesh with operating gear wheels 52 mounted to revolve upon the transverse shaft 53 (see Figs. 2 and 9); but the gear wheel which is shown in Fig. 2 is not the gear wheel with which the registering segments 50 mesh but is a companion gear wheel of the same size mounted side by side with the operating gear wheel as shown in Fig. 9. It will be seen by reference to this latter figure that for each of the five registering segments for the five banks of amount keys there is a series of three companion wheels mounted side by side on the shaft 53, the middle one of each of these series being as before mentioned, the gear wheel 52 which will be called the operating gear wheel,. and the right-hand one (which is seen in Fig. 2) is the printer gear wheel 140 and the lefthand one is the counter gear wheel 141.

Upon the forward movement of the register-- ing segment 50 by the depression of any key, its corresponding operating gear 52 is rotated but this has no effect upon its cornpanion coimter and printer gears because the same are not at this time connected;

but upon the return of the registering segment 50 to normal position in the manner described, the operating gear 52 is coupled up to both its companion gears 140 and 141 by means of an idle pinion 142 (see Figs. 8 and 12) which is mounted upon a collar 143 journaled upon the transverse shaft 144 which shaft is mounted between arms 145 which are pivoted upon a shaft 146. One of these arms has a rearwardly extending portion 147 (see Fig. 14) from which projects an anti-friction roller 148 which runs in a cam groove 149 formed in a disk 150 fast upon the upper operating shaft 38, the shape of the cam groove being such that upon the rotation of the shaft 38 the idle pinion is rocked forward into mesh with the gear wheels 140, 52 and 141, the width of the idle pinion being enough to span all three of these gear wheels, and of course there being a separate idle pinion for each of the five sets of triple gear wheels as shown in Fig. 12. liy an arrangement which will be later described, the shaft carrying these idle pinions 142 is arranged to be laterally displaced by means of the operation of the special keys so that when they are rocked into mesh with the afore-described companion gear wheels they will couple up only the printer wheel to the operating gear wheel and will not couple up the counter gear to the operating gear and consequently the counter will be thrown out of opera tion.

To continue with the operation of the counter, it will be seen that the idle pinions 142 are thrown into mesh with the triple companion gears at the beginning of the operation of the machine and consequently as soon as the registering segments 50 are restored to normal position the revolution of the operating gear 52 will through the idle pinions 142 also cause the revolution of the printer gear 140 and the counter gear 141. The printer gears are by means of nested sleeves 151 (see Fig. 9) connected to appropriate printing wheels to be later described. Meshing with the counter gears 141 are the pinions 152 (see Fig. 8) of the summary total counter, these pinions being mounted upon a transverse shaft 153, and thus 1t Wlll be seen that the successive operation of the countergears 14:1 are transferred to the summary total 'counter pinions 152. These pinions do not have numerals upon their peripheries to enable the operator to tell at a glance how much the amount of registration has been but it is intended that this amount be determined by *means of printing as will later be described.

Journaled upon a transverse shaft 154: extending above the summary total counter are the pinions 155 of the grand total counter, these pinions having fast to them disks 156 bearing numerals to designate the total amount of registration as shown in Fig. 10. This shaft 154 is carried between the side arms of a rock frame 157 which is mounted upon a rock shaft 158, this shaft being aclaptedto be rocked at each operation of the machine-to rock the frame 157 downward and thereby carry the pinions 155 of the grand total counter into mesh with the pinions 152 of'the summary total counterso that the movements of the summary total counter by the registering segments 50 will also be transferred to the grand total counter, and since the grand totalcounter is disconnected from the summary total counter by the return-of the rock frame '157 at each operation of the machine, it will then be possible for the summary total counter to be reset to Zero independently of the grand total counter. The means for rocking the shaft 158t0 throw inthe grand total counter as just explained comprises a downwardly extending arm 159 (see Fig. 11-) which is fast to said rock shaft and at its lower end carries an anti-friction roller 160 which lies in the path of a cam 161 fast to the upper operating shaft 38, so that upon the-operation of said shaft by the operation of the machine the arm 159 is carried rearward thereby rocking the frame 157 downward to carry the grand total counter into mesh with the summary total counter. The frame 157 is returned to normal position by means of a spring 162 attached to'the arm 159.

Transfer mechanism.-Suitable transfer mechanism is provided for both the summary total and the grand total counters as follows, (see 'Fig. 8). The transfer tripping pawls 165 for the summary counter are pivoted upon a transverse shaft 166 and are spring pressed forward by means of springs 167 suitably seated ina stationary cross bar of the machine. Each summary counter wheel is provided with a transfer ratchet 168 and the forwardly extending nose of the tripping pawl 165 is arranged to be engaged by the-ordinary transfer pin of the counter wheels, this pin not being shown herein but its construction and operation being easily understood as being part of the well known construction of transfer mechanism. Pivoted upon a transverse shaft 169 is a rock frame 170 carrying at its lower end an antifriction roller 171 which projects into a cam groove 172 formed in a disk 17 8 fast to the upper-operating shaft 38. The upper end of the frame 170 carries a series of summary counter transfer pawls 17 4 which are pivoted at 17 5 and extend forward over the summary itotal counter. The forward end of each of these transfer pawls carries a lug 176 which coiiperates with a shoulder 177 formed upon the tripping pawl 165. Besting upon the rearward ends of the transfer pawls .175 :is a transvere shaft 178 mounted in a rock frame 179 which, as shown in Fig. 18, is also pivoted upon the transverse shaft 169 and has a downwardly extending arm carrying a pin 180 which projects into a cam groove 181 formed in a disk fast to the operating shaft 38. Springs 182 seated below the rearward ends of the transfer pawls 174 normally force these pawls upward against the shaft 178.

The operation of these devices is as follows: Upon :the operation of the shaft 38 the rock frame 170 is thus rocked rearward as will .be seen from the shape of the cam groove 172 .and thereby the transfer pawls 17 1 are rocked rearward and the lugs 176 formed on the forward ends thereof become seated on the shoulders 177 of the tripping pawls and now upon the operation of the counter wheels if any tripping pawl is tripped by its transfer pin, the shoulder 177 will be withdrawn from the lug 176 and the transfer pawl will drop down to engage the transfer pinion 168, but of course in the meantime to permit this dropping down of the transfer pawl 17 1, the shaft 178 has to be rocked forward, this being accomplished by the shape of the cam groove 181 shown in Fig. 18; and upon the completion of the operation of the machine, the continued rotation-of'sthe shaft 38 carries the rock frame 17 0 again forward and thereby the transfer pawls which have been tripped will effect the necessary transfer.

The transfer mechanism for the grand total counter comprises tripping pawls 183 pivoted upon a transverse shaft 18%, above which-extend the transfer pawls 185 which are pivoted between disks 186 journaled upon a transverse shaft 187, these pawls being normally drawn downward by means of springs 188. A link 189 connects the disks 186 to the rock frame 170. The forward end of the transfer pawls have hooked noses arranged to engage the transfer pinions 190 fast to the grand total counter wheels, and the rearward ends of the transfer pawls are formed with downwardly extending tails 191 which are engaged by a dog 192 1nounted on the transfer shaft 158, the rearward divided legs of which dog straddle the aforesaid shaft 178 carried by the rock frame 17 9. The middle portion of each transfer pawl carries a lug 193 arranged to normally rest fee upon the shoulder 194 of the tripping pawl 183.

The operation of these parts is as follows: )Vhen the rock frame 170 is rocked rearward in the manner above described, the rearward movement of the link 189 rotates the disk 186 to carry the transfer pawls 185 forward, and the simultaneous forward 'movement of the transverse shaft 178 acts upon the legs of the dog 192 to withdraw the nose of the dog from the tails 186 and thereby permit the transfer pawls 185 to drop until the lugs 193 rest upon the shoulders 194 of the tripping pawls 183; and then upon the operation of the grand total counter the ordinary single transfer pins which are not shown herein but which are similar to those de scribed for the summary counter and of course are well understood without further description, strike the tripping pawls and rock the same rearward sufliciently to withdraw the shoulders 194 from under the lugs 193 to permit the transfer pawls to drop still farther so that their noses engage the transfer pinions 190 and upon the final return movement of the rock frame 170 the link 189 is again carried forward to rotate the disks 186 and also draw rearward the transfer pawls 185 to effect the transfer for those wheels where the transfer has been set; and the return of the shaft 178 to normal position returns the dog 192 to normal position and hence returns the transfer pawls 185 to normal upper position.

Throw-out for the 002mter.Upon the operation of any one of the three special transaction keys 32 for the transaction Recd. on Acct, Chg, and Pd. Out it is desirable to prevent the operation of the counter as'is usual in machines of this class, and to effect this there is provided a lever 200 (see Fig. 6) pivoted to one of the main tie bars of the machine at 201, and this lever extends rearwardly and at its rearward end has pivoted to it a horizontal extending rod 202 (see Fig. 12) which rod is at its other end attached to one of the arms 145 of the frame which rocks inward the idle pinions 142, as has already been described with reference to the setting of the counter wheels and printer wheels by the registering segments (see Figs. 8 and 14). Referring again to Fig. 12 it will be seen that the lever 200 has a downwardly extending projection 203 which is arranged to be engaged by the beveled ends of the special keys 32 tobe rocked about its pivot in such manner as to force the rod 202 to the left in Fig. 12, and thereby the arm 145 is forced to the left against the tension of the spring 204 and since this arm 145 is fast to the shaft 144 (see also Fig. 8) upon which are mounted the collars 143 and the idle pinions 142 it will be seen that the entire shaft 144 is shifted laterally to the left thereby also carrying to the left the other arm 145 which has therearwardlyextending arm 147 which carries the roller 148 for rocking the idle pinions 142 into mesh with their gear wheels as already described with reference to Fig. 14. The right hand end of the shaft 144 (lookingin the direction of Fig. 12) is suitably counter-bolted so that the right hand pinion may turn freely upon said shaft, but with the shifting of the shaft to the left the ninion'will be carried bodily with the shaft, this counter-bolting being a well known construction and not described further. Thus it will be seen that when any one'of the specialtransaction keys is depressed the en-. tire shaft 144 carrying the idle pinions 142 is shifted laterally to-such an extent that the pinions 142 when rocked forward simply couple up the operating gear 52 to the printer gears 140 and do not couple the gears 52 to the counter gears 141, and thus upon the operation of any one of the special keys it will be seen that the summary total counter will not be operated and of course neither will the grand total counterbe operated.

The length of the pin l48which projects into the cam groove 149 for the purpose of rocking the idle pinions 142 forward, is such that upon the shifting of the shaft 144' in the manner just described, the pin 148 will not be withdrawn from the cam groove but will still remain in engagement with the same. Printing wheeZs.The printing wheels controlled by theamount keys are set by means of nested sleeves 151 (see Fig. 9) already described as being connected with the printer gear wheels 140, these nested sleeves 151 being connected with intermediate gear wheels 210 (see Fig. 12) which in turn mesh with gear wheels 211 which are attached at the ends of nested sleeves 212 which carry the amount printing wheels 213 mounted upon the shaft 214. There are also amount printing Wheels for printing the amounts of'higher capacity than the ordinary registering amounts as will be later explained, these high capacity wheels being necessary for the sake of printing the amounts registered upon the grand total,

of special keys 32, 33 and 34 is shown in detail in Fig. 13. As already explained, thev differentially operated detent plates 135 (see Fig. 23) which cotiperate with these three banks of keys have formed upon their upper ends the aforesaid teeth 137 which mesh with i the pinions 138. The two pinions 138 shown at the right in Fig. 13 are for the two clerks numerals banks and the pinion 138shown at the left is for the bank of special keys, and the latter pinion is connected by a sleeve 220 to an operating segment 221 which meshes with a pinion 222 fast upon the side of the
